The sewer had apparently been abandoned for years, it was pitch black, the plumbing system was rusted with holes everywhere, a strong smell of rust floated in the air, and the sound of water droplets dripping was constantly ringing. In this quiet sewer, even the sound of dripping water can be heard very clearly. Walking in such a place made Xia Chiyu shudder.

"Where's the Iceman?" Burning Man checked it while leading them forward, but he didn't find his good friend at the scene, so he couldn't help but ask. The woman who pierced the wall paused and replied, "He's fighting X, giving us time......"

"I have a bad feeling about this place, it's so dark, the vision is too poor and it's relatively narrow, and I think it's dangerous if there is a boss fight." Gu Qinyan also found a problem at this time, just like Xia Chiyu.

"yes, and considering that X's poisonous form was able to crawl on the wall like a gecko, I think this place will be very dangerous." Lacey chimed in.

"If the other party has night vision again...... I feel like I'm going to hehe. Su Xing said with a dry smile.

Although Xia Chiyu can summon a ball of light to illuminate his vision, the spell cannot last forever, and this sewer pipe is too narrow, their team is dragged for a long time, and it is not very convenient to take care of the front and back, and it is not good if the people in the rear are attacked.

"I have goosebumps when you say that...... Lin Qianxue touched her arm and muttered.

"It's scary, let's get out of this place quickly, brother!" Li Feifei ran to Xia Chiyu's side, hugged his arm and said closely, her face turned pale with fright.

"Even if you tell me so, it's someone else who leads the way." Xia Chiyu said with a dry smile.

At the moment when the atmosphere eased slightly, there was a sudden sound of "Bang Dang!" from overhead. There was a crisp sound, and then the ground above his head suddenly corroded into a hole. Then a black shadow fell from the sky, and everyone suddenly screamed, and hurriedly took a step back.

But the black shadow is not X, but the iceman who was left to fight X.

At this moment, there was still a lot of yellow-green slime flowing from the iceman's body, and a faint green smoke was wafting from him. And the Iceman is actually in the form of ice at this time. His body is in a state of ice, but the yellow-green venom on his body is still corroding his body, which shows that this venom can be dissolved in water and is in a high temperature state.

"Being able to synthesize a new venom, is that what you mean......" Xia Chiyu muttered to himself.

"Iceman, no!" The fire man immediately wanted to go up to check the status of his friend, but the woman who wore the wall hurriedly pulled him down: "No! He has venom on him, and if you touch it, you will be poisoned! ”

As she spoke, the woman who pierced the wall grabbed the fire man, and then stretched out her hand to Xia Chiyu and the others, "Quick." Catch me! We must get out of this place quickly! X must already be around here, ready to attack us at any moment......"

Before the words fell, a black shadow hung in the air like Spider-Man, falling behind the woman who pierced the wall like a ghost, and it was X, who was in the form of fierce poison. X resembles a humanoid gecko, with a naked, unusually slender and fragile body, but a terrifying poison sticking to its entire body. He landed behind the woman who walked through the wall. Pierced the neck with his thumb to the wall-piercing woman.

The woman who pierced through the wall suddenly let out a coquettish cry, and then instantly fell to the ground. Unconscious. X, on the other hand, quickly returned to the darkness, and the burning man cursed angrily, raised his hand and spewed out a large flame that illuminated the scene, and X's figure flashed in the shadows behind him, quickly dodging the fire. Hidden back into the shadows.

The Burning Man turned around and spewed flames as he advanced, shouting, "Go!" Come on! Follow this sewer, and the beast will pick you up and take you to the lab! I'm going to stay and avenge them both! ”

"Grab your lunch. Farewell. Wake muttered quietly, of course he didn't dare let Nadya hear it.

"Let's go, take advantage of him to help us stall for time, and get out of this place quickly, this environment is too unfavorable for us, and it is dangerous to fight here." Xia Chiyu said, and planned to move forward with everyone. But at this time, X coldly rushed out of the flames of the burning man, and stabbed his index finger in the burning man's chest, and it was clear that the slime outside his body could still prevent fire.

The Burning Man snorted, then quickly fell to the ground, but still struggling slightly. X leaned over and stabbed the burning man in the neck with his thumb, and then the burning man stopped moving. Xia Chiyu noticed at this time that X had indeed stabbed the burning man with different fingers, and it seemed that this guy had different fingers and different effects of the venom injected.

"Damn, what kind of revenge is this talking about, it didn't even help us delay for a minute!" Wake up and say angrily.

"There's no way, it looks like there's bound to be a boss fight here." Xia Chiyu said helplessly and turned around.

However, instead of fighting them head-on, X quickly returned to the shadows after taking the Pyro.

"I'm so scared, eat fish ......" Zhang Zinuo hid behind Xia Chiyu, trembling and said, "I always feel as if it will appear behind me at any time, I am restless, what should I do?" ”

Xia Chiyu raised his hand and summoned two balls of light, letting them hover around the team to ensure that everyone could stay in the light, but there was a "poof!" from the darkness. Then a mouthful of thick black venom hit one of the balls of light, and the ball of light went out instantly, leaving only one ball of light to circle around them.

In this way, half of them will be kept in the dark. And Xia Chiyu estimated that this was probably the mode of the BOSS, and it would definitely ensure that there were players exposed to the dark, no matter what skills were used, so he could only remind: "This can only be done first, this BOSS seems to be like this at this stage, we have to beware of its sneak attack." ”

"And this boss doesn't seem to be afraid of fire attribute damage and ice attribute damage, but that state should be very vulnerable to physical damage. So, leave it to me. Gu Qinyan said lightly, "I'll go out as a bait." ”

"Can you? It feels like it's going to be dangerous. Su Xing asked with a frown.

But Xia Chiyu knew that if someone could do it, it would probably only be Gu Qinyan. Gu Qinyan's reaction in this team is definitely outstanding, and of course Nadya's reaction is also very fast, but her ice attribute damage should have no effect on X, so now Gu Qinyan is the best candidate.

"Good. Then it's decided to sell you. Xia Chiyu nodded and said, "You are a level ninety swordsman, even if this poisoning hurts, it shouldn't kill you in seconds, so don't worry." ”

Gu Qinyan nodded and took the initiative to stand in the shadows outside the crowd. Reach out and press it on the hilt of the sword at your waist. He keeps his knife drawn, apparently ready to use a flash to fight back against the boss.

The crowd continued to move forward, and in order to minimize the number of X appearances, they went as fast as they could. Gu Qinyan kept the knife drawn and followed closely, waiting for X's next ambush.

However, X did not pick on Gu Qinyan, but launched an attack on Li Feifei, and the ghostly figure appeared behind Li Feifei the moment the ball of light passed by Li Feifei's side. And Li Feifei herself didn't realize it at all.

Fortunately, Xia Chiyu found out, he waved his hand to find a vine and dragged Li Feifei over.

After everyone found out that X appeared in the crowd, the girls suddenly let out a scream, and Tatsukaze immediately swung his sword and slashed at X, but although X had low defense but reacted extremely quickly, he immediately lowered his head to dodge, and then quickly crawled away like a spider. Disappeared into the shadows.

"It's dangerous...... Xia Chiyu sighed secretly.

"Good reaction......" Gu Qinyan also breathed a sigh of relief, "I haven't reacted yet." How did you ......"

Xia Chiyu explained: "I don't rely on reactions...... Based on the previous X-attack on the wall-piercing girl, I assume that he usually picks the target with the least HP in the team, and it must be when the target shifts his gaze. ”

"So you're eyeing the crispy profession in the team?" Su Xing laughed dryly, "Only you can think of this, so it seems that X is indeed planning to pick on the most vulnerable players." ”

"Is it intended to keep reducing our numbers so that it is easier to start? Boy...... The AI is so high. Chen Feng couldn't help but sigh. At this time, Lacey replied: "Then why don't I be responsible for killing the boss?" ”

"Right...... The power of sacrifice. Xia Chiyu was suddenly stunned. Then grinned: "I have a way......"

Everyone continued to move forward, and soon, X picked the next target, and he appeared behind Liu Yiyu. In fact, almost no one reacted this time, waiting for Xia Chiyu to find out. X's thumb was about to be attached to Liu Yiyu's neck, but at this time, Xia Chiyu suddenly raised his hand and aimed at Liu Yiyu to release the time slowdown.

In an instant, X and Liu Yiyu both fell into a state of deceleration, while Reis methodically released the power of the sacrificial knight to Liu Yiyu, and then put on a posture and used a royal flash, turning into a ray of light that flashed from X's body in an instant.

X was hit by a royal flash, his health instantly decreased by more than half, and he flew backwards, rolled around on the ground, and the moment he got up and stabilized, Gu Qinyan had already come to him, and the long sword slashed out two half-moon rays, and then raised it to bring out a full moon-shaped sword. This time, the Half Moon Slash and the Full Moon Slash directly knocked out the remaining health of the boss.

X let out a wail, his body melting, and the black liquid enveloped him again, turning back into the Overlord's Egg state. Seeing this, Xia Chiyu finally breathed a sigh of relief, since the boss had returned to the state of the overlord's egg, indicating that they had a safe time again, everyone immediately accelerated forward.

However, Xia Chiyu is also a little worried, it is safe to let the BOSS enter the Overlord's Egg state like this, but it will also make the BOSS accelerate the pace of evolution, will it cause any problems in the end......

But now Xia Chiyu couldn't care so much, and after a while of everyone advancing along the sewer, they encountered a beast that had been waiting for a long time in front of them. A humanoid with blue hair and a genius scientist.

As soon as the beast saw them, it asked, "I heard from the Iceman that you had an encounter with X in a poisonous state, has anyone been poisoned?" I have an antidote here, as long as he is not dead, he can remove the poison. ”

"So that's what it means...... Xia Chiyu frowned and said helplessly, it is obvious that X does intend to consume them on that road, but as long as they are fast enough and maintain the blood volume of the poisoned player, they can reach the beast in time, they can remove the poison from the player's body, so this is actually an escape mode, and there is no need to beat the BOSS back to the egg state.

"Great, no one has been poisoned, let's hurry forward, the lab will go down this way!" The beast spoke, reaching out and grabbing the hatch on the ground, and jumped down first. Xia Chiyu and the others also followed, and because there was a safe time, the beast explained to them the next stage of the task process on the way.

And it sounds like the next stage is not so simple.

"Listen, we're heading to Dr. Lister's lab, where only robots, sentinels, mechanical dogs, and mechanical bats are left now. I'll be directing you to the lab in the main control room to find the Reversal of Evolution Potion, you'll run into multiple obstacles along the way, X will try to snipe you, and you'll have to try to get there alive. ”

"X also has a 'parasitic mode', where he is able to parasitize himself, or part of his body, on any living being and control them, and after X evolves, even the automatons are no exception, so all mechs will be your enemies. And in the end, you still face the most difficult problem, which is to inject the reversal potion into X. ”

"Ah, at that time, it was the final boss battle, and I believe that this is only the process of cleaning up the mobs." Xia Chiyu sighed secretly.

The crowd followed the beast, and soon came to a gate, and the beast pressed the lock in front of the door a few times, and the gate let out a "snort!" With a sound, it slowly opened. As soon as he entered, the beast pointed to his left and said, "The security room is over there, I will go in and deal with the enemies inside, and then guide you inside." ”

As he spoke, the beast threw itself on the ground, ran fast on all fours, and soon disappeared into the aisle.

On Xia Chiyu's side, not long after the beast left, a dull roar sounded behind him.

"Ah, I knew it was this urine ......" Su Xing sighed, and in the shadows behind him, X's sturdy figure slowly appeared, and his health was twice as high as when he appeared the second time!

X was in the same power pattern as he had appeared in the second appearance, and he bent down, as if intending to crash into it. At that time, Xia Chiyu secretly screamed that it was not good, at this moment they were all in this narrow passage, and the gate in front of them was closed, they had no way to escape, and this collision would hit all of them!

But at this critical moment, the heavy iron door suddenly and quickly closed.

"Bell!" A bell rang, and the steel gate, which was nearly half a meter, was slammed out of a hole. Then the beast's voice rang out from the loudspeaker above them: "This can only stop him for a while, now let's go!" (To be continued.) )
